The disclosure relates to a method for performing a random access procedure between a user equipment and a radio base station. The UE is configured with at least one unlicensed cell having an unlicensed cell frequency, via which the UE performs the random access procedure bandwidth. A minimum frequency bandwidth threshold is defined for transmissions via the unlicensed cell. The user equipment selects a random access preamble sequence for the random access procedure. A frequency bandwidth is determined by the UE for transmitting the random access preamble sequence via the unlicensed cell, the determined frequency bandwidth of the random access preamble sequence being at least the minimum frequency bandwidth threshold. The UE then transmits the random access preamble sequence to the radio base station such that at least the determined frequency bandwidth of the unlicensed cell is occupied.
A method for performing a random access procedure between a user equipment and a radio base station in a mobile communication system, wherein the user equipment is configured with at least one unlicensed cell, the random access procedure being performed via the unlicensed cell having an unlicensed cell frequency bandwidth,
A radio base station for performing a random access procedure with a user equipment in a mobile communication system, wherein the user equipment is configured with at least one unlicensed cell, the random access procedure being performed via the unlicensed cell having an unlicensed cell frequency bandwidth, wherein a minimum frequency bandwidth threshold is defined for transmissions via the unlicensed cell, wherein a frequency bandwidth is determined for the user equipment to transmit the random access preamble sequence via the unlicensed cell, the determined frequency bandwidth being at least the minimum frequency bandwidth threshold, and wherein the radio base station comprises:
A user equipment for performing a random access procedure with a radio base station in a mobile communication system, wherein the user equipment is configured with at least one unlicensed cell, the random access procedure being performed via the unlicensed cell having an unlicensed cell frequency bandwidth, wherein a minimum frequency bandwidth threshold is defined for transmissions via the unlicensed cell, and wherein the user equipment comprises:
